The current invention pertains to a novel and improved form or style of refractory blocks or tiles'designed more or less for general use but particularly adapted for employment in a protective'wall-mounted on the inner surface of the metaLorsteel shell of a tank, vessel, or comparable receptacle'to shield and protect such container from the effects of overheating-and from the consequences of the presence of a condensate which would otherwise be likely to cause deterioration and ultimate failure of the metal wall of the vessel or chamber if allowed to form thereon.

The invention pertains more especially to refractory-tiles used for the proper preservation of carbon-steel shells or walls of storage-hoppers, chambers, reactor-cham bers. hot-gas and catalyst piping and hot-air piping employed in the catalytic-processes in the hydrocarbon chemical industry.

In order to enable those skilled in the art of refractory tiles and protective walls to understand this invention and the advantages accruing from its employment, a present preferred embodiment of the invention has been illustrated in detail in the accompanying drawing to which reference should be had in connection with the following description and in which drawin the same parts or elements in the several views have been designated by like reference characters.

In this drawing:

Figure 1 is a perspective View of the new tile;

Figure 2 is a longitudinal, central section through the tile;

Figure 3 is a fragmentary perspective view looking somewhat upwardly at the lower end of the tile;

Figure 4 is a top plan view of the tile; and

Figure 5 shows the manner of mounting this form of tile, this figure illustrating the top portion of one such tile and the bottom portion of the next higher tile.

As is clearly portrayed in the drawing, the novel and unique tile, composed of a single integral member, includes a back or outer, generallyrectangular section or portion II and a similar, parallel, front or inner section or portion I2 olfset or displaced somewhat laterally or transversely of the companion part II, thereby providing along one longitudinal edge of the tile, a lengthwise rib I3 forming part of the rear section I I and supplying along the opposite edge of the tile a complementary, lengthwise space I4 of substantially the same dimensions as those of the rib and adapted, in the completed wall to receive the rib or the next adjacent tile, the illustrated rib I3 1 Claim. (o1. 72 25) til ' work and a part of another 2' being designed to fit in the ous tile; whereby like tiles with offset joints between them.

As is'shown, the back-section I I is somewhat thicker than the displaced front-section I2, and I5 of the lat-1 ter and the terminal, bottomdepending portion the extreme, top, upstanding part I6 of the front-section areboth of substantially equal thickness slightly less than that of the main intermediate body of such forward section I2, the front face of which is flush throughout.

The rear surface of the back-section and the front face of the forward-section are substantially parallel as illustrated.

As is clearly presented, the top of section II and a minor part of the top of section I2 are shaped to unitedly form a double-depth groove parallel with the rear and front surfaces of the tile, open at both opposite ends. and having a partially-curved surface I1, a flat bottom I8. an upright surface I9. a plane elevated surface 2|, and a final erect surface 22, the top faces of parts I I and I5 being on substantially the same plane at a right-angle to the lengthwise dimension of the In use. the deep portion of such groove receives a depending flange of a horizontal retaining metal-bar 31 and the fiat surface 2| and the top part of I5 support an intermediate refractory-tile 43 of the shape and style shown in Figure 5,

which illustration also depicts a section of a metal column 3| and a section of insulation II.

The bottom of section I I and a relatively-minor portion of the part I6 are cut away or omitted to provide a groove 23 parallel to the front and back surfaces of the tile. substantially-rectangular in cross-section. and open at both ends. it being noted that the part It extends down a short distance further than the bottom surface 24 of section II, the latter at this position constituting a depending rib 25 rectangular in crosssection.

In the finished protective-wall, such bottom groove 23 accommodates an upstanding flange of another supporting metallic-bar of the frameof the intermediate tiles referred to.

The novel tile under detailed consideration is so constructed that each of its parts performs a valuable function either in positioning the tile in place in the wall or in the completed wall itself.

This application constitutes a continuation in part of my co-pending patent application Serial groove of its contigu-i may be fitted together:

I 3 No. 470,992, Lined containers, filed January 1, 1943.

Obviously, the invention, as set forth in the appended claim, is not necessarily limited and restricted to the precise structural details shown and described and these may be modified somewhat, without departure from the substance and essence of the invention and without the loss of its substantial benefits and advantages.

I claim:

A solid refractory-tile substantially longer than its width and thickness and having a rear rectangular parallelepiped section and a front rectangular parallelepiped section parallel and integral with said rear section, said front and rear sections being offset laterally with relation to one another providing an outstanding rib,

edge of the tile and a" the opposite longitudinal along one longitudinal correlative space along edge of the tile adapted to receive the corresponding rib of a like tile, theedges of each ofi-. setliaving planeiparallel surfaces, .the upper end of the tile having a grooveparallel to the "front and back surfaces of the .tile, said groove having two, parallel communicating longitudinal parts of 'difieren't depths, the greater depth part of said groove being located in and extending the full width of said rear sectionjand being to the "tile having a groove parallel rear of the lesser depth part of the groove, the rear wall of said greater depth part being curved longitudinally forwardly downwardly of the tile for the purpose of bracing strength, the bottom of said lesser depth part of said groove being located in both sections and being a plane surface at a right angle to the front surface of the tile,;the front wall of said lesser depthlpart of said groove being a plane'surface parallel to front surface of the tile, the bottom end of said to the front and back surfaces of the tile, and the bottom end of said front section of said tile extending lengthwisebeyondthe corresponding end of said rear .sec'tionof the tile.
